LOOSE-LEAF- BINDER.

' {LAND and CARL FLBRENNE, citizens of the United Statesyresiding .a'tPortland, in the .county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Loose-Leaf Binders, of which thefollowing is a specification.

- Our invention may be considered asan improvement over that set forth in an application for Letters Patent, filed May 26th, 1914; Serial No. 841145, allowed November 11th, 1914, and relates to binders for holding loose leaves or sheets, and particularly to that class of binders having separable covers, and has for its object the provision of a punching attachment integral with one for both of said covers, whereby the sheets .to be bound may readily be punched correctly to receive the binding posts or staples. lVe attain'the above object by means of the construction herein described, and illustrated in the accompanying drawing, which therefore forms a part of-this application for Letters Patent, and in which Figure 1 is a fragmentary perspective view of a binder embodying our invention. Fig. 2 is a transverse section of one cover embodying our invention. Fig. 3 is a perspective view. partially broken away, of the punching'eyelet. Y

Like characters of reference indicate like parts throughout the several views of the drawing, in which the numeral 1 is one cover, designated for convenience, the lower cover, and 2 is the other cover, designated for convenience, the upper cover. Said covers are formed of book board 3, or other suitable material, covered with cloth, paper, leather or other suitable material 4. Each cover is provided with a hinge portion 5 flexibly connected to the cover by means of the material 4, as shown at 6.

A flap or hinge cover 7 is flexibly connected to each hinge portion by means ofthe material 4, as shown at 8, said connection being upon that edge of the hinge portion opposite that by which said hinge portion is connected to the cover. By means of its flexible connection the flap 7 is adapted to fold over the hinge 5 until the outer surface of said flap lies in. substantially the same plane as the outside surface of the cover, as shown in Figs. 1 and 2.

Staples 9, of soft malleable material, are Secured to the hinge portion of cover 1 and Patented 111M214, 1916.

"Application filed March 29, 1915. Serial No. 17,812.

. areadapted toenter and protrude through orifices 10 1n hinge 5 of cover2. By first passing said staples throughthe sheets to be bound and'then through orifices 10, and

bending said staples down upon the hinge portion 5, as shown in Fig. 1, the sheets will be firmly confined within or between the covers.

In order to present a neat and finished exterior appearance, we provide a flexible back portion 11 which may be of the same material 4 as is used upon the covers. Said flexible back portion is secured within a pocket 12 provided in cover 1, and is adapt- -ed to surround the hinge portions 5 with thelr flaps 7 and enter a pocket 13 provided in cover 2. Flap 7 of cover 2 is provided rwith eyelet punches adapted to register with orifices 10 in the hinge portion 5. Said eye- 'let punches, of any suitable metal, are formed with a body portion 14, a knife or punch portion 15, and attaching ears 16, as shown in Fig. 3. Said eyelets are secured upon flap 7 by passing ears 16 through the same and turning saidears over, as shown in dotted lines at 16" in Fig. 3. When said eyelets are attached to flap 7 the knife or punch portion 15 of the eyeletis passed entirely through the flap, as shown in Fig. 1,

and allowed to protrude normally to same. and a position to register with orifices 10 i when flap 7 is turned down upon hinge portion 5. By placing the sheets 17 to be bound upon the outside surface of cover 2. flap may be used as a guide for bringing the edges of sheets 17 even. and then by forcibly turning flap 7 down, the knives or punches 15 will perforate the sheets and enter orifices 10, as shown in Fig. 2. The perforated sheets 17 may then be placed over the staples on cover 1, cover 2 placed in position over said staples, and the staples turned down, as shown in Fig. 1, when the sheets are firmly bound between the covers. The back portion 11 may then be inserted in pocket 13, and a neat and serviceable binder results.

Our invention may be made of any size, and constructed of any material deemed suitable and convenient for a device of this character, and while we have illustrated and described a preferred form of construction and arran ement of parts considered advisable in materializing our invention, we wish to include in this application for Letters Patent all mechanical equivalents or substitutes that may fairly be considered to come Within the scope and purview of our invention as herein illustrated and described, and defined in the appended claims.

Having illustrated and described our in vention so that others skilled in the art to which it appertains may be enabled to construct and use the same, What we'claim as new and desire to secure by Letters. Patent, is 1. A loose leaf binder comprising a duality of separable covers, a hinge portion flexibly attached to each of said covers, a flap flexibly attached to each of said hinge porsaid covers, flaps flexibly attached to said hinges, ductile clips adapted to oppositely engage the perforations in said hinges and to hold loose leaves intermediate said hinges, said flaps being adapted to fold over upon said hinges and to cover said ductile clips.
